Title:
誘導負荷を有する回路網に発生した電流の推移に対する反作用を低減する方法及びブースト変換器
Document Type and Number:
Japanese Patent JP4188444
Kind Code:
B2
Abstract:
The method involves using active filtering of the harmonics through a boost-converter. An inductive load is used as at least a part replacement of an inductance needed for the boost-converter. The load is a motor which is driven through a switching bridge. At least one motor winding is used as the inductance for the boost-converter. The function of the boost-converter is integrated in the switching bridge driving the motor and in the motor, whereby a motor winding is used as an inductance for the boost-converter. The motor winding magnetises in a first phase with a voltage of a condenser (5), in a second phase through an electronic switch for power factor correction and in a third phase the motor winding is demagnetised.
